Define needed functions

Source some external functions

source(here('R', 'functions', 'filterClicks.R'))
source(here('R', 'functions', 'loadMultiBinaries.R'))
source(here('R', 'functions', 'plotContours.R'))
source(here('R', 'functions', 'clickSummary.R'))

# if not using Rproj/here package use:
# source(file.path(params$path_code, 'R', 'functions', 'loadMultiBinaries.R'))

Load and prep AcousticStudies

Load existing PAMpal AcousticStudy object for event processing. They were saved as .RDS files so must be read in with readRDS rather than load.

These were not filtered, so will need to be filtered using filterClicks.

# load existing AcousticStudy 
detsAll <- readRDS(detsFile)
# cat('Loaded', detsFile, '\n')

# summarize how many events
nEventsAll <- length(names(events(detsAll)))
# cat(nEventsAll, 'original events\n')

spCodes <- c('31', '32', '33', '36', '37')
bfList <- list()
for (sp in 1:length(spCodes)){
  spCode <- spCodes[sp]
  bfList[[sp]] <- filter(detsAll, species == spCode)
}
dets <- bindStudies(bfList)

nEvents <- length(names(events(dets)))
# cat(nEvents, 'single species blackfish events\n')

# these files will NOT have the correct binary paths so have to update them 
# (this is slow...)
dets <- PAMpal::updateFiles(dets, bin = path_to_binaries, db = path_to_db)

# filter AcousticStudy
detsFilt <- filterClicks(dets)

# number of events may change after filtering (all clicks may be filtered out)
nEventsFilt <- length(names(events(detsFilt)))

# cat(nEventsFilt, 'filtered, single species blackfish events\n')

Loaded //piccrpnas/crp2/McCullough/PAMpal/Acoustic_Studies/2017_HICEAS_1706_ch5.rdata, filtered AcousticStudy to only blackfish events and cleaned up bad click detections:

298 events total for all species, 32 events for blackfish only, and 32 events after filtering.

Load reference spectra, if specified

Load the reference spectra for plotting, if set with refSpecList.

# refSpecList is specified in YAML params. Can be one or multiple species
# for single species specify as char string without quotations e.g., refSpecPc
# for multiple species, specify with call to R and c()
#     e.g., !r c('meanSpecGm', 'refSpecPc_LLHARP') 

if (!is.null(refSpecList)){
  refSpecs = list()
  for (rs in refSpecList){
    refSpecs[[rs]] = read.csv(file.path(path_to_refSpec, paste0(rs, '.csv')))
  }
}

Event summaries

Loop through each detection event (n = 32) and process/filter detected clicks, create plots, and calculate summary statistics. This step works at two levels - on the level of an AcousticStudy object, and on a data.frame of extracted click data from that AcousticStudy object.

for (iEvent in c(1:nEventsFilt)){
  # iEvent = 6 # for testing
  # ("pagebreak \n")
  
  # extract this event UID string
  eventList <- events(detsFilt)
  eventUID <- names(eventList)[iEvent]
  
  # set header for this event and print time
  cat('\n\n#### Event ID:   ', names(eventList)[iEvent], '  |   Species:   ',  
      eventList[[iEvent]]@species$id, '\n')
  cat('Time:   ', format(eventList[[eventUID]]@ancillary$grouping$start, 
                         '%Y-%m-%d %H:%M%Z'), ' to ',
